Definitions

  • a novel method for assembling layers of piece goods using piece goods from at least two rows of piece goods on a transfer area is specified.
  • Piece goods and especially sacks are often combined into specific packaging units and, for example, stacked together in several layers on transport pallets, wrapped together in protective transport film as required and then stored or transported further.
  • Stacking of such piece goods is usually carried out using so-called palletizers.
  • An essential component of such palletizers is a device for assembling layers of piece goods, which are then placed one after the other on a lifting device that carries a pallet.
  • a certain number of piece goods are initially arranged as a piece goods layer with a certain layer pattern and then this piece goods layer is transferred to a transport pallet. After this, another piece goods layer with a different layer pattern can be assembled, with this additional piece goods layer then being stacked on top of the previous layer on the pallet.
  • the individual pieces of goods or their respective layer patterns can, for example, be rotated relative to each other or stacked crosswise on top of each other. In this way, stacks of pieces of goods with several pieces of goods, each with a different layer pattern or with alternating layer patterns, can be placed on a pallet, whereby the stacks of piece goods are relatively stable and the piece goods are stacked next to each other or on top of each other with as few gaps as possible.
  • a first row of piece goods is usually conveyed from one side onto a sliding surface of the device for assembling the layers of piece goods using a feed belt. It is then usually necessary to use a slider to push the first row of piece goods placed on the sliding surface one position further in order to be able to use the same feed belt to serially transport a further, second row of piece goods and, if necessary, then at least an additional, third and/or fourth row of piece goods to form a layer of piece goods, also onto the sliding surface.
  • the two or more rows of piece goods placed one after the other are arranged on the sliding surface to form a layer of piece goods with two or more rows of piece goods lying next to one another, if necessary with multiple intermediate actuation of the slider to move the rows of piece goods.
  • the two or more rows of piece goods arranged next to one another which are thus arranged together on the sliding surface in accordance with a layer of piece goods, can then be moved further together by the slider onto a transfer surface.
  • the piece goods layer can finally be transferred to a pallet located below the transfer area.
  • the disadvantage of such devices known from the prior art for assembling layers of piece goods is at least that the serial feeding of the two or more rows of piece goods, which together form a layer of piece goods, with a single feed belt one after the other onto the sliding surface is time-consuming.
  • a further time disadvantage is due to the fact that the slider has to be operated several times in between in order to move the two or more rows of piece goods, which have been introduced serially onto the sliding surface, in a suitable manner to form a layer of piece goods with rows of piece goods lying next to one another.
  • the aforementioned design variants of devices for assembling layers of piece goods have one disadvantage in common: the entire layer of piece goods, made up of two or more rows of piece goods lying next to one another, is moved from the sliding surface to the transfer surface using a common slider.
  • one slider disadvantageously pushes piece goods one after the other from the two or more rows of piece goods lying next to one another in the entire layer of piece goods from the sliding surface, which can lead to damage and deformation of the piece goods.
  • the overall palletizing quality is impaired due to the joint pushing of an entire piece goods layer with a common or a single pusher, since the layer pattern of such a jointly pushed piece goods layer is usually irregular and can have undesirable gaps and free spaces between neighboring piece goods units. Individual piece goods units can only be insufficiently fixed within the piece goods layer in question, which is why individual piece goods layers are pushed towards each other. and such a stack of general cargo has insufficient stability for further transport.
  • palletizing quality refers to the quality with which a stack of items with several layers of items is placed on a pallet, whereby the individual layers of items can be stacked as two or more layers of items on top of each other as stably as possible and where the items are stacked next to each other or on top of each other with as few gaps as possible.
  • the printed publications DE 2017 118 928 A1 as well as WO 2019/076708 A1 Devices for assembling layers of piece goods have become known, in which two or three rows of piece goods are transported from the same side in an orthogonal formation in relation to a conveyor surface to one and the same side edge of the conveyor surface, in order to then be gripped piece by piece from this side edge by a manipulator in the form of a gantry robot or kinematic robot in a clamping, force-locking and/or form-locking manner and to be positioned on the conveyor surface in a position spatially separated from the formation of the respective row of piece goods.
  • a manipulator in the form of a gantry robot or kinematic robot in a clamping, force-locking and/or form-locking manner and to be positioned on the conveyor surface in a position spatially separated from the formation of the respective row of piece goods.
  • these designs are both time-consuming and costly due to the necessary use of a robot manipulator.
  • the publication EN 101 11 680 A1 a device for palletizing piece goods to form a piece goods stack has become known, in which two piece goods rows are simultaneously moved from two opposite side edges onto a layer conveyor belt arranged between them. Together with two further piece goods rows, each of which is positioned to the side next to the two piece goods rows arranged centrally on the layer conveyor belt, this piece goods layer, which is formed from four piece goods rows arranged next to one another, is conveyed further onto an additional, downstream conveyor belt by means of several parallel conveyor belts, after two stops, which are directed against the flow of the piece goods, have been moved laterally out of the movement area of the finished piece goods layer.
  • one of the objects of the invention is to propose a device for assembling layers of piece goods using piece goods from at least two rows of piece goods, which, when used in conjunction with palletizers, is suitable for producing at least one stack of piece goods with several layers of piece goods, and with which, on the one hand, the stacking performance of currently known devices of this type can be further increased and, on the other hand, the palletizing quality can be further improved in order to be able to stack pieces of piece goods into corresponding stacks as quickly and as gently as possible.
  • a further object of the invention is to propose a novel method for assembling layers of piece goods from at least two rows of piece goods on a transfer surface.
  • a device for assembling layers of piece goods mentioned at the outset in that the sliding device further comprises a first alignment slide and a second alignment slide for lateral alignment of the piece goods placed on the transfer surface, wherein the first alignment slide is arranged along a third side edge of the transfer surface and the second alignment slide are arranged along a fourth side edge (158) of the transfer surface (152) opposite the third side edge, and wherein the two alignment slides (176, 178) are movable in mutually opposite directions (AU1, AU2).
  • the device for assembling layers of piece goods comprises at least one second feed device for feeding the number of piece goods of at least a second row of piece goods to a second feed position which is different from the first feed position.
  • the second feed device ensures that piece goods of the second row of piece goods are conveyed independently of piece goods of the first row of piece goods to a second feed position on a second side edge of the transfer surface of the transfer device, wherein the second feed position is adjacent to a second side edge of the transfer surface which is different from the first side edge.

  • the number of piece goods in the second piece goods row can be pushed off with the second pusher in a particularly gentle manner in this arrangement, since the pushing path for each piece goods in the second piece goods row from the second feed position to the second transfer position is as short as possible.
  • the second piece goods row is pushed off with the second pusher transversely to the longitudinal direction of the piece goods row.
  • the pushing off from the second feed position to the The second transfer position can therefore take place without individual cargo units being pushed forward against each other, thus avoiding unwanted damage to the cargo.

  • the second side edge to which the second feed position is adjacent, can be arranged at an angle to the first side edge, preferably orthogonally or at a right angle to the first side edge.
  • the first and second feed positions are therefore at an angle, preferably at a right angle, adjacent to each other and adjacent to two adjacent side edges along the transfer surface.
